Energy From Your Tranquil Pond
November 30, 2007 11:24 am | Blogs | CommentsEnergy News: There are biofuel critics who say America can never grow enough raw material for the technology to be affordable and ubiquitous, but some scientists believe algae is a better option. At the University of Minnesota, they're figuring out how to make algae grow very fast, and how to get up to 15,000 gallons of oil per acre -- that is 750 percent more yield than
DC/DC Dimmer for LED Lighting Products Supports 5V DC to 40V DC, Up to 2A
November 30, 2007 8:58 am | Product Releases | CommentsLEDtronics announced the release of its DC/DC Dimmer for LED lighting products, supporting 5V DC to 40V DC applications up to 2A or 24W. LED-DIMMER-001 is suited for LED strip lights, LED bulbs and LED floodlights. Since LEDs draw less current than traditional incandescent bulbs, one had to buy a special high-end electronic dimmer to control the desired light levels for their LED lighting application.

Do Silicon Carbide Schottky Diodes Make Silicon Rectifiers Obsolete?
November 29, 2007 7:02 am | by John Jovalusky, QSpeed Semiconductor | Articles | CommentsPower factor is the ratio of the actual power used to the apparent (reactive) power that a piece of equipment draws from the alternating current (AC) line. The reactance of large capacitors or inductors can cause the apparent power drawn from the line to exceed the actual power used, resulting in low power factor (PF). The lower the PF, the more energy is lost along the AC power line. The result is higher electricity bills for the utility customer. That lost energy also lowers the capacity of the utility distribution system.
